i. Excretion
in this function the liver is aided by the kidney
deamination i.e. excess amino acids converted into urea and uric acid which is transported to skin and kidney for removal
detoxi?cation where harmful substances are converted into harmless ones in the liver and transported to kidneys for removal
breakdown of worn out blood cells and haemoglobin and the residue excreted through the
kidney to give urine a yellow tinge
Breakdown of sex hormones after they have performed their function and the wasted are
released through the kidney and bile.
ii) Homeostasis
regulation of blood glucose
the normal amount of glucose in blood is about 90mg/ 100
increase in blood sugar is detected by cells of the pancreas which secrete insulin
insulin stimulates the liver to convert excess glucose to glycogen
further excess glucose is converted to fats until the normal blood sugar level is attained
Excess glucose is oxidized to carbon IV oxide, water and energy. Excess glucose is also used in respiration
decrease in blood sugar level below normal level is detected by the pancreas, which secretes glucagon which stimulates the liver to convert glycogen to glucose until the normal sugar level is attained
fats, amino acids are converted to glucose
it also leads to reduced oxidation of glucose
Deamination
excess amino acids are deaminated by the removal of amino group
the amino group is converted to ammonia
ammonia combines with carbon IV oxide to form urea
urea is excreted in urine through the kidney
Detoxification
poisonous substances are converted to less harmful compounds
Thermal regulation
maintenance of body temperature
heat is generated in the liver by chemical activities
the heat is distributed
